Modeling vehicle-pedestrian interactions in the road environment is essential to develop pedestrian detection and pedestrian crash avoidance systems. In this paper, one novel approach is proposed to estimate the vehicle-pedestrian encountering risk in the road environment based on a large scale naturalistic driving data collection. Considering the(More)
As active safety system features are being introduced to the passenger vehicle market segment, there is an immediate need to develop a standardized testing protocol and scoring mechanism which enables an objective comparison of similar active safety system performance as implemented across various vehicle platforms. It is desirable that this standard is(More)
Pedestrian PCS (pre-Collision System), as a novel active pedestrian safety equipment to reduce pedestrian fatalities, was introduced by several vehicle manufactures in recent years. How to evaluate this system is still in study. This paper describes the development of a set of mannequins for pedestrian PCS evaluation. These mannequins represent relevant(More)
Crash imminent braking (CIB) systems are equipped in high-end passenger vehicles by many auto manufactures. Due to the complex nature of the CIB technology, the features and performance of various CIB systems differ significantly. To date, there are no standards to evaluate and compare the comprehensive performance of different CIB systems. This paper(More)
Vehicle forward collision imminent braking (CIB) systems have been equipped in high-end passenger vehicles by many auto manufactures. Due to the complex nature of the CIB technology, the features and performance of various CIB systems differ significantly. As to date, there are no standards to evaluate and compare different CIB systems. This paper describes(More)
As Crash Imminent Braking (CIB) systems have been introduced to the passenger vehicle market segment, there is an immediate need to develop a standardized performance scoring system which enables an objective comparison of similar CIB systems implemented across various vehicle platforms. It is desirable that this standard is adopted by the entire automotive(More)
Forward pedestrian collision imminent braking (CIB) systems has proven to be of great significance in improving road safety and protecting pedestrians. Since pedestrian CIB technology is not mature, the performance of different pedestrian CIB systems varies significantly. Therefore the simulation of a CIB system needs to be vehicle specific. The CIB(More)
Joint loading is a recently developed mechanical modality, which potentially provides a therapeutic regimen to activate bone formation and prevent degradation of joint tissues. To our knowledge, however, few joint loading devices are available for clinical or point-of-care applications. Using a voice-coil actuator, we developed an electromechanical loading(More)
In the US, the number of traffic fatalities has had a long term downward trend as a result of advances in the crash worthiness of vehicles. However, these improvements in crash worthiness do little to help protect non-motorists. Over the last few years, this has been reflected in the number of pedestrian fatalities increasing in both absolute and relative(More)
Vehicle to Vehicle (V2V) communication systems enable vehicles to communicate with each other and use the shared information to make safety related decisions. However, the safety improvement of the current V2V systems only benefits V2V-enabled objects in the V2V network. The Pedestrian Automatic Emergency Braking System (PAEB) can utilize onboard sensors to(More)
